Employment contracts in the UK: what employers should include

A clear employment contract gives both sides a reliable record of what has been agreed. It should cover the statutory written particulars and any additional terms that matter to the role, business and working arrangement.

Start with the required particulars

Employees and workers are entitled to a written statement of their main terms from the first day of work. Employers should record the parties' names, start date, pay and payment interval, hours and days of work, holiday entitlement, place of work, job title or a description of duties, and the length and conditions of any probation period.

Other particulars can be provided in instalments within the statutory timeframe. These may include pension arrangements, collective agreements, non-compulsory training and information about disciplinary and grievance procedures. Use the current GOV.UK written statement checklist before issuing the document.

Describe the real working arrangement

The strongest contract is specific enough to be useful without promising flexibility the business cannot deliver. Describe the employee's main duties, reporting line and level of responsibility. If duties may reasonably evolve, explain that in proportionate language rather than using an unlimited catch-all clause.

State the normal place of work and any genuine remote, hybrid, travel or mobility expectations. If the employee will work at client sites or across several locations, explain the usual base, expense arrangements and reasonable boundaries. For hours, distinguish normal working time from overtime, on-call duties, shift patterns and any flexibility the role genuinely requires.

Pay wording should identify salary or hourly rate, payment date and method. Record how commission, bonuses, tips, overtime or allowances work and whether each element is contractual or discretionary. If a benefit is subject to provider rules, say so. Clear drafting here prevents a headline salary from being undermined by uncertainty about variable pay.

Add terms that protect clarity

A fuller contract may also explain confidentiality, intellectual property, deductions, expenses, benefits, absence reporting, data protection responsibilities and how contractual changes will be handled. Only include post-termination restrictions where they are genuinely needed and appropriately drafted.

Write for the actual role rather than copying a generic job title. Pay particular attention to variable hours, remote or hybrid work, commission, overtime, mobility and any fixed end date. Our guide to contract types explains how the structure changes for different arrangements.

Connect the contract to workplace policies

The contract does not need to reproduce every procedure. It can point to a handbook for detailed absence reporting, holiday requests, data security, expenses and conduct rules. Make the contractual status of those policies clear. Accidentally making every operational procedure contractual can make routine updates difficult; treating an important promise as non-contractual can create the opposite problem.

Check all connected documents together. The offer letter, contract, job description, bonus plan and handbook should use the same start date, pay, hours, holiday and notice provisions. If one document takes priority when wording conflicts, explain that hierarchy.

Think through endings as well as beginnings

Good contracts address notice from both employer and employee, payment in lieu where appropriate, garden leave if required, return of property and obligations that continue after employment. Confidentiality clauses should protect genuine confidential information rather than attempting to prevent ordinary use of an employee's skills and experience.

Any post-termination restriction should be tailored to a legitimate business interest, the employee's actual role and a reasonable period and scope. Generic restrictions copied into every contract may be difficult to justify. Specialist drafting is sensible where client relationships, sensitive information or senior influence create a material risk.

A reliable issue process

Use a short quality-control workflow for every hire:

• confirm employee status, contract type and start date;
• reconcile the document with the approved offer;
• check role-specific pay, hours, location and duties;
• attach or link the current policies and job description;
• allow questions and correct genuine errors before acceptance;
• record the final accepted version and its date;
• schedule any probation, fixed-term or visa follow-up dates.

Electronic acceptance can be practical, but retain an audit trail showing which version was accepted. Limit access to personnel files and keep records according to the organisation's retention and data-protection approach.

Common drafting mistakes

Frequent problems include leaving template alternatives in the final document, using a full-time holiday figure for a part-time worker, naming the wrong employing entity, contradicting the offer letter and describing a fixed workplace when the role was sold as remote. Another common error is adding broad discretion everywhere: a clause still needs to be clear enough for the employee to understand the commitment.

Before the employee signs

• Check every term matches the offer and recruitment discussions.
• Remove clauses that are irrelevant to the role.
• Make contractual and non-contractual policies easy to distinguish.
• Give the employee time to read the document and ask questions.
• Keep the accepted version and record later agreed changes.

Revisit the contract when pay, hours, location, duties or benefits change. Our guide to changing contract terms explains consultation and written confirmation.
